MOLD-FORM STRUCTURE.

Application filed August 2, 1927. Serial No. 210,199.

This invention relates to forms or molds by means of which concrete orother plastic material is shaped to form walls and other similarstructures, and constitutesan improvement over the type of constructionillustrated in my prior United States Letters Patent, No. 1,574,636.

Briefly stated, the present invention provides as an important feature,a corner mold form characterized by the employment of angularly disposedconverging articulated side wall sect-ions terminatingat either side of'the corner angle extremity, these sections being completed by an anglemember presenting a vertically extendingiiller of approximate V-shape incross section forming the corner angle of the mold and constituting acontinuation of the adjacent side sections. Bracing means are employedto support and maintain the filler in cooperative relation to the sidesections.

As an additional feature, the. invention provides means for alining andjoiningv abutting or superposed sections of the mold, one form of whichprovides means for bracing that section of the mold to which it isattached.

Other objects and advantages will be apparent during the course of thefollowing description.

In the drawings accompanying and forming part hereof and in which apreferable embodiment of the invention is illustrated Fig. l illustratesa. corner mold structure of the present invention with upper and low ersuperposed corner sections shown separated to disclose the coopera-tivearrangement and interior features.

Fig. 2 is a top plan view of such a mold used in connection withadjacent ends of a building under construction and illustrating themanner of bracing the corner angle members.

Fig. 3 is a vertical section on an enlarged scale taken on the line 3*?)of Fig. 2.

Fig. 4 is al horizontal section on an enlarg ed scale through one of thecorner angle members illustrating the coaction of its filler with theadjacent side wall sections of the mold.

Figs. 5 and 6 illustrate different forms of anchoring abutments for thelower ends of turn-buckle braces.

The illustrated articulated mold is of the type illustrated in my priorpatent above referred to, the articulated sections comprising parallelform boards 2 arranged in horizontal courses based upon a suitablesupport such as the foundation l and held in alinement, and againstdisalinement through pouring, by tie wires 3 in the form of elongatedloops extending between adjacent courses at appropriate points withtheir ends projecting beyond the outer faces of the form boards 2 as att, and locked in position by a series of vertical locking rods 5, theprojecting ends i-of the tie Wires being, of course, in verticalalinement. So far as the purposes of the present invention areconcerned,the particulalform of tie wire is immaterial.

In a corner mold with which the present invention is more particularlyconcerned, vthe articulated sidewall sections of the mold are disposedin converging angular relation to provide the corner mold structure. Theinside mold boardv members of this structure, which as seen in Fig. l,are braced adjacent their meeting angle by tie Wires and locking rods,have their complement-al side memers brought together so ,as to abut, asat 6 and 7, this junction of the sections providing the inside corner ofthe mold. It is not necessary to provide a nished edge at this point,but at the outer side of the mold, a finished corner angle is highlydesirable. In accordance with the present invention, the outerconverging side walls of the mold terminate at opposite sides of theouter corner extremity of the mold structure and a sep arate filler' isprovided for this portion of the mold. One form which this ller maytalre, provides a unitary angle member projecting outwardly from thecorner of the mold with divergent angular sides 8 and 9 braced bytriangular cleats 10 and having connected appropriately to their inneredge, a vertically extending V-shaped filler 11 alining with theconverging outer side wall sections of the mold to form a continuationthereof and the outer corner angle of the mold. The base of this anglemember is fixed in proper position in the mold structure by appropriatemeans. In the drawings, in the lower section of the mold. in which thebase courses rest up'on the foundation l, blocks 12 at the outer sidesof the angle boards 8 and 9 of this member are appropriately anchored tothe base or toundation 1 in positions deiining the proper posit-ion forthe base of the angle member' which may be secured to these blocksthrough nails or screws inserted through these angle members.

lVhere in pouring a wall corner, it is desired to pour an additionalsection before a lower section has been set, a second mold section, asshown in Fig. 1 of the drawings, is superposed over the base section.The side wall sections ot' these two superposed units will be alinedthrough the employment of longer locking rods 5 and in order to securethe angle members 8-9 of the upper section to and in alinement with thelower angle members, joint plates ot novel construction are provided. Asshown in Fig. 1 at the upper portion of the .lower section ot the mold,the top edges ot the angular sides 8-9 of the angle members are embracedby substantially lJ-shaped plates 13 bolted through the sides thereofand provided with upstanding pins or dowels 14:. n The base of thesuperposed angle members 8-9 will be embraced at alined points bysimilar U- shaped plates 15 bolted thereto and having sockets 16 formedtherein to receive the dowels 14 ot the section next below. The jointplates 13, being positioned upon the divergent sides oi the anglemembers will unite these superposed members in proper alinement, theadjacent side mold sections being similarly alined through the rods 5.

The upper li shaped joint plates 1.3 tor embracing the upper edges o1the divergent sides 8 and 9 ot the angle members ot' the mold formsectionV are formed, as best seen in Figs. 2 and 3, with biiurcatedoffsets 17 forming ears between which eyes 18 are journalled. These eyesserve as pivot links to which the upper biturcated ends ot turnbuclrlebrace rods 19 are pivotally connected. These brace rods extend from theoutside of the divergent sides 8-9 ot the angle members diagonallydownward in opposite directions, their lower ends being anchored to asuitable abutment, which as is shown in Figs. 5 and 6 and in Fig. 1, maybe formed by the head ot a bolt or nail 2O extending in or through atube 2l spacing the lower courses of the inner and outer wall sectionsot the mold, the lower section ot the turn-buckle being 'formed as aneye 22 through which the bolt or nail anchor 20 extends.

In the lower halt uji-Fig. 1 ot the drawings, a modified form of abracing member is shown, this form constituting diagonal brace bars orboards 23 nailed to the outer edges ot the divergent side angle members8 and 9 and similarly anchored at their bases to blocks 24 which in turnare anchored to the base support 1. While this form may be used on thebase section, the turn buckle negaron brace previously described is of amore permanent nature and is equally a; iicable to the lower course ofthe mold structure.

rl`he angle members forming the corner angle of the mold, as described,therefore constitutes a movable mold corner element, which may be movedfrom ins'tallat' n to '.istallation and used over and over again. Thecorner and edge molding surface provided by its tl-shaped iiller piecewill prosent an unbroken line or sui-'tace throughout its height, and asmooth edge finish tor the corner can be secured.

Vlien a corner is first poured and the side walls are nent to beextended, it is desirable to provide the poured side walls with someshoulder or abutment to which the next section poured may be joined. lhave secured this result and improved the molding operation by providingend closures for the side sections of the corner mold form, these moldcorners being in the form of iiller mold boards 25 sized and shaped toclose the ends oli the mold sections and provided on their inner sideswith groove-forming ribs QG, the outer edges of the filler beingibothbraced and fixed in position by veV ical cleats 27. The end closuredescribed will form with its rib 26, a. groove in the poured section otthe mold which when set will provide shoulders against which theconcrete in the next poured section will abut and set. llhile l haveherein described a specific embodiment of the invention, it will beunderstood that various modifications and adaptations thereot will bepermissible within the spirit ot the invention and the scope of theappended claims.
